QR Code

A Quick Response (QR) code uses a square arrangement of dark and light modules to store data. In practical marketing it often represents a web address: a customer scans a code on packaging, signage or printed mail and opens the linked page. The destination should be useful on a mobile device and deliver what the surrounding call to action promises. A QR code itself does not measure visits or prove that a purchase occurred.

For campaign measurement, teams may embed a short tracked URL or use a managed redirect whose destination can be changed later. Static codes directly encode a fixed value; so-called dynamic codes commonly point to an intermediary URL that can be redirected. That flexibility adds reliance on the redirect provider. Test the printed size, contrast, quiet zone, scanning distance and destination before distribution, and include a readable URL for people who cannot or prefer not to scan.

QR codes are not automatically safe. A malicious code or substituted sticker can send visitors to a deceptive destination. Readers should inspect the displayed address before submitting credentials or payment details. Avoid promising that QR codes alone improve search rankings or reveal every offline customer's identity.
